Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish population

Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayis University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008: a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. Conclusion: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. © Medicina Oral S. L

Regional odontodysplasia of the deciduous and permanent teeth associated with eruption disorders : a case report

Regional odontodysplasia (RO) is an unusual, non-hereditary anomaly of the dental hard tissues with characteristic clinical, radiographic and histological findings. Clinically, RO affects the primary and permanent dentition in the maxilla and mandible or both jaws. Radiographically, there is a lack of contrast between the enamel dentin, both of which are less radiopaque than unaffected counterparts. Additionally, enamel and dentin layers are thin, giving the teeth a ?ghost-like? appearance. Histologically, areas of hypocalcified enamel are visible and enamel prisms appear irregular in direction. Coronal dentin is fibrous, consisting of clefts and a reduced number of dentinal tubules; radicular dentin is generally more normal in structure and calcification. The RO etiology is uncertain; numerous factors have been suggested and considered as local trauma, irradiation, hypophosphatasia, hypocalcemia, hyperpyrexia. The treatment of RO has given rise to controversy. These cases require a continuous and multidisciplinary approach. Most clinicians advocate extracting the affected teeth as soon as possible and inserting a prosthetic replacement. Other clinicians prefer restorative procedures, if possible, to protect the affected erupted teeth. A case of RO in an 8 year-old male whose chief complaint was the absence of eruption of permanent teeth is presented. Clinical, radiographic and histological findings are described

Multiple unerupted mandibular permanent molar teeth: a case report

<p>The multiple impacted teeth at jaws are a rare condition that frequently associated with syndromes, metabolic disorders or trauma. A 48-year old male patient was referred to our clinic, with complaint of pain on right retromolar region while chewing. The patient had facial asymmetry and restricted mouth opening. Clinical and radiographic examination revealed the impaction of mandibular first, second and third molar and an abnormal condyle and coronoid process. All of the impacted teeth were extracted. Because the patient refused other treatment procedures no surgical intervention was performed for the asymmetry and restricted mouth opening. Six months clinic and radiographic follow up were satisfactory.</p&gt

FLORİD SEMENTO-OSSEÖZ DİSPLAZİ: OLGU RAPORU [Florid Cemento-Osseous Dysplasia: A Case Report]

ÖZET Florid semento-osseoz displazi, nadiren gözlenen, genellikle çenelerin dişli alanlarında yerleşen, benign, fibro-osseöz bir lezyondur. Orta yaşta kadınlarda ve mandibulada daha sık gözlenirler. Çoğu florid semento-osseoz displazi lezyonu sekonder enfeksiyon meydana gelinceye kadar asemptomatiktir ve rutin radyografik muayenede tesadüfen ortaya çıkar. Bu vaka raporunda, 29 yaşındaki bayan hastada, klinik, radyografik ve histolojik bulgular temel alınarak teşhisi konulan florid semento-osseoz displazi olgusu sunulmuştur. ABSTRACT Florid cemento-osseous dysplasia is a rare benign fibro-osseous lesion in the tooth-bearing regions of the jaws. It is more commonly seen in middle-aged women and the mandible. Many florid cemento-osseous dysplasia lesions are asymptomatic lesions until secondary infection occurs and it was discovered accidentally on routine radiographic examination. In this report, a case of a 48 years old woman, who was diagnosed with florid cemento-osseous dysplasia depends on clinical, radiological and histological findings is presented

ARTERIOVENOUS MALFORMATIONS IN THE DIFFERENTIAL DIAGNOSIS OF PALATAL SWELLINGS*

An arteriovenous malformation (AVM) is composed of abnormal communications between arteries and veins without the normal intervening capillary bed. AVM of the head and neck is a rare vascular anomaly. We present here an unusual case of AVM with the size of 4x3 cm at the left posterior palatal area. Incisionel biopsy revealed AVM. Resection of the lesion following angiography was suggested to the patient however, he refused the treatment. The patient was considered to be under control. AVM should always be kept in mind in the differential diagnosis of palatal swellings

BİLATERAL MANDİBULAR DİSTOMOLAR DİŞLER: VAKA RAPORU [Bilateral Mandibular Distomolar Teeth: A Case Report]

ÖZET Sürnümerer dişler normal diş sayısından fazla olan dişler olarak tanımlanmaktadır. Aksesuar bir dördüncü molar diş gibi üçüncü molar dişin distaline lokalize olmuş sürnümerer dişler distomolar dişler olarak adlandırılırlar. Maksillada ve erkeklerde daha sık gözlenirler. Bu dişler, komşu dişte maloklüzyona malpozisyona, çürüğe ve kök rezorpsiyonlarına neden olabilirler. Ek olarak, yarı gömülü distomolarlardan kaynaklı perikoronitis ve dentigeröz kistler meydana gelebilir. Bu nedenlerden dolayı çekilmeleri veya uzun süre takip edilmeleri gerekir. Bu çalışmada, nadir gözlenen bilateral distomolar dişlere sahip 28 yaşındaki kadın hasta sunulmuş ve tedavi yaklaşımları değerlendirilmiştir. Anahtar kelimeler: Distomolar, Sürnümerer Diş, Mandibula ABSTRACT Teeth in excess of the normal number are referred to as surnumerary teeth. The surnumerary teeth located distally to the third molar as an accessory fourth molar are termed distomolar teeth. They are seen mostly in maxilla and males. These teeth may cause malocclusion, malposition, caries and root resorption of adjacent teeth. In addition, pericoronitis and dentigerous cysts may also occur due to partial embedded distomolars. For these reasons, these teeth are needed to be extracted or long-term follow-up. A rare case report of 28 years old female with bilateral distomolar teeth is presented in this study and evaluated the treatment approaches. Keywords: Distomolar, Surnumerary Tooth, Mandibl

DEEP NECK INFECTION AFTER THIRD MOLAR EXTRACTION*

Odontogenic and oropharyngeal infections are relatively common in the cervicofacial region. In rare cases, odontogenic or peritonsillar abscesses may spread through the deep fascial cervical spaces and cause life-threatening complications. Odontogenic infection is the most common cause of deep neck infections and it accounts for 43% of the cases. Early diagnosis, immediate antibiotic treatment, and surgical drainage are the basis of therapeutic success. Deep neck infections are potentially life threatening complications if they are not diagnosed in time and treated quickly. This case report presents clinical, radiological features and treatment of the spread of abscesses through cervical spaces of an unusual case of deep neck infection that was caused by the secondary infection of the root remnants after extraction
